The Sum Of Two Numbers Is 54 And Their Difference Is 16

The problem given says that 2 unknown numbers are given, whose sum is equal to 54 and the difference is 16. Let's find the two numbers :

When we add the two numbers :
X + Y = 54

The difference of two numbers :
X - Y = 16

Solution :

If we add the two equations eachother , then we can find the first number.

X + Y = 54
X - Y = 16

2X = 70

Let's divide 70 to 2 for the first number "X" .

X/2 = 35

First number is 35

X + Y = 54
So ;
35 + Y = 54
Y = 54 - 35
Y = 19

Second number is 19
